Just a tip for you guys needing to install those wear rings, get a bowl of hot water, hot to the point you cant stick your hand in it, drop the ring in it, wait until the water cools to where you can bare sticking your fingers in, pull the ring out, put the tapered side towards the radiator, and tap it with a wood block and hammer. Once you have it flush with the harmonic balancer dowel, put your harmonic balancer back on and evenly run the bolts in, this will suck the wear sleeve in the rest of the way. And for the love of god, make sure your small low pressure oil pump gear is on before you put the sleeve on.
